Anth 2200 Lab 2 Part One: Mendelian Combinations show your work 1. What peroent of one's offtspring would be heterozygousit a homozygous dominant 2. What peroent of offspring would be heterozygous if a homazygous recessive individual mated with 3. What percent of offspring would be homazygous recessive if two heterozygotes mated? 4. What percent of offspring would be heterozygous if two heterozygotes mated Achondroplasia is a dominant trait. Individuals who have it have a particular form of dwarfism. If two non-dwarfs have a child with this dwarfism, what are the genotypes of each parent and the offspring? Explain. 5. Watch out for this one. It is very difficult

Explanation / Answer

We have choose one character - T and t

Then Homozygous dominant individual - TT.

Homozygous recessive individual - tt.

Heterozygous individual - Tt.

1) Cross between Homozygous dominant and  Heterozygous individual.

TT X Tt

Gametes formed T and T T and t.

Next generation  

% of one's offspring would be heterozgous - 50%.

2) Cross between homozygous recessive with heterozygous individual.

tt X Tt

Gametes formed t and t T and t.

Next generation

% of heterozygous offsprings - 50%.

3) Cross between two heterozyotes

Tt X Tt

Gametes formed T and t T and t.

Next generation

% of homozygous recessive offspring - 1/4 = 0.25 x 100 = 25%.

4) % of heterozygous offspring - 1/2 = 0.50 x 100 = 50%.

Male/ Female T T T TT(Homozygous dominant) TT(Homozygous dominant) t Tt(Heterozygous) Tt(Heterozygous)
